Contradiction with Luke 12:48
The principle of being rewarded based on what one has been given opposes the submission of less in Luke 19:18.
Luke 12:48: But he that knew not, and did commit things worthy of stripes, shall be beaten with few [stripes]. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more.
Contradiction with Matthew 25:29
Emphasizes an opposite outcome for the one who has less, differing from Luke 19:18's presentation.
Matthew 25:29: For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath.
Contradiction with Proverbs 13:11
Suggests growth and multiplication of wealth by diligence, while Luke 19:18 references only yielding more from a modest gain.
Proverbs 13:11: Wealth [gotten] by vanity shall be diminished: but he that gathereth by labour shall increase. [by labour: Heb. with the hand]
Contradiction with 2 Corinthians 9:6
Emphasizes sowing and reaping which contrasts with the modest input-output relationship shown in Luke 19:18.
2 Corinthians 9:6: But this [I say], He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully.
